IMPROVEMENT IN ORNAMENTAL CHAIN-LINKS.

Specification forming part of Letters Patent No. 2 I 8,963, dated August26, 1879; application filed July 10, 1879.

. To all whom it may concern:

Be it known that I, JAMES L. HEELEY, of Attleborough Falls, in thecounty of Bristol and State of Massachusetts, have invented a new anduseful Improvement in Ornamental Chain-Links, which improvement is fullyset forth in the following specification, reference being had to theaccompanying drawings, in which Figure 1 shows my link partly in sideview and partly in section. Fig. 2 is a cross-section thereof. Fig. 3 isan end view of the same.

Similar letters indicate corresponding parts.

My invention relates to the construction of box-links for vest or otherchains, with the View to dispense with soldenand will first be describedwith reference to the drawings, and then pointed out in the claims.

The parts of mylink are side plates, A, end collars, B, an innercylinder, O, and central bar, D.

The side plates, A, are ornamentally perforated but they may, ifdesired, be left solid, and left plain or engraved in any desiredmanner. The longitudinal edges of the plates A are beveled or mitered,and they are put together edge to edge, thereby forming a box, in whichposition they are held by the collars B. These collars B are fitted onthe box formed by the plates A, and are situated at the respective endsof the-link, as shown.

In this example four of the side plates, A, are used, each'having a flatcross-section, the whole forming. a square box; but, if desired, thenumber thereof may be increased or diminished, the box taking acorresponding shape, and by bending the plates crosswise I am enabled toemploy as low as two plates. In some cases the plates A are twistedspirally between their ends.

The cylinder 0 is fitted into the space between the plates A, and ispreferably formed of a wire coil. The primary function of thiscylii'lder G is to center the bar D, which latter passes through thelink, and is bent at each end to form coupling-loops c, that impinge onthe ends of the plates A, and thus prevent their longitudinaldisplacement.

When the plates A are perforated, the cylinder (l is visible throughtheir perforations,

cylinder 0 also has the effect of sustaining the plates A in theirproper relative positions, and

when it is used the longitudinal edges of the plates may be left square,the edge of one plate being, in that case, brought up to or against theside of another.

When the edges of the plates A are mitered,

and more than two plates-are used, the loops e are arranged at or overtheir joints, as shown in Fig. 3, thereby impinging upon. each of theplates.

It will be seen that thelink above described is destitute of solder, oneresult of which is, that labor is saved in the construction of thearticle, and another that the parts may be finished separately beforebeing put together, so that different plating may be used in the samelink.

It may be remarked that by shaping the ends of the box formed by theside plates, A, accordingly, a different shape may be given to thecollars B than the cross-section of the intermediate portion of the box.One or more of the side plates, A, moreover, may be provided with swellsor elevations to prevent longitudinal displacement of the collars.

lVhat I claim as new, and desire to secure by Letters Patent, is

1. A chain-link consisting of side plates with mitered edges arrangededge to edge, two collars, one at each end of the link, for holding theplates together, and a bar extending through the link, having two loops,one at each end, impinging on the ends of the plates at their joints,substantially as described.

2. A chain-link consisting of side plates arranged edge to edge,collars," one at each end of the link, for holding the plates together,a cylinder within the side plates, and a bar extending through the link,having two loops, one at each end, impinging on the ends of the plates,substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 25th day of June, 1879.

JAMES L. HEELEY.
